I'm earning a little from autoblogs but goddamn it was hard work to setup. And to call them "auto" is a bit of a misnomer, still have to upgrade plugins, fix fuck ups, pay for hosting, respond to angry people about ripped content, etc. The more successful ones I have are from established domains and are monetised with EPN and Adsense. But just the effort involved in finding an established domain almost negates autblogging as a means of serious income for me. It's a bit of a numbers game too, you'd want to aim to have 100's or 1000's of autoblogs to survive on it. Definately a viable means of income though, just a bit of a grind.
